Hello,
I am currently doing photometry on single drizzled WFPC2 images of globular clusters. The cosmic rays have been flagged at 100000 and the datapars datamax is set to avoid these high values. Setting the datamax works to avoid these high values works for DAOFIND and PHOT. When it gets to PSTSELECT it selects stars that are above the datamax value that has been set.
How will the PSF task be affected if it uses these stars?
Also I am finding that if I set the psfrad to values higher then 8 it results in a poor subtracted image from allstar.
Any help/comments would be greatly appreciated.
